Patent DE-3627913-A1 (DE)
Title: Pallet transporter, in particular electrically driven pallet transporter
Inventor: SIEPER HORST
IPC: B62D51/00
Filed: 1986-08-16
Abstract: The invention relates to an electrically driven pallet transporter for pallets which have, on one side, a wheel pair of their own and supports opposite said wheel pair. Energy is supplied by a battery belonging to the transporter. The transporter is hooked in on the support side of the pallet and the supports are lifted off the ground by pivoting the transporter downwards. Consequently, 50% of the pallet load always acts on the two drive wheels of the pallet transporter, it being possible to disengage said wheels by hand. Owing to this arrangement of the drive wheels, the pallet transporter, sterred by the operator on a control bar belonging to the transporter, can transport the loaded pallet via muddy slopes and into right-angled openings, which is not possible with the prior-art transporters owing to single-wheel or two-wheel drive with a ground pressure which is too low and a turning radius which is too large due to the long distance of the drive wheel or steering wheel from the pallet. The transporter according to the invention can, in addition, be produced more cost-effectively. Main application areas: in agriculture where feeding passages are narrow, industry, towing aircraft and trailers.

Patent DE-3639929-A1 (DE)
Inventor: ROOS FRIEDRICH
IPC: F26B25/22
Filed: 1986-11-22
Abstract: The invention relates to a continuous dryer for veneer. In addition to temperature sensors near the inlet and middle zones to determine heat demand and to control heat input in these zones, the dryer also has an infrared detector at the exit end to determine surface temperature and thus to determine residual moisture of the veneer. The signal from this infrared detector is processed to give a control signal for blowers in the drying zones near the exit. By this means, more precise and reliable control in final moisture is achieved. Variations in dryer load, initial moisture, wood density, and sheet thickness can be better tolerated.

Title: Magnetic flow meter for fluid media
Inventor: DAMM ROLF DIPL ING
IPC: G01F1/115
Filed: 1987-02-03
Abstract: The invention relates to a magnetic flow meter for fluid media, preferably for service hot water measurement in residential, industrial and business buildings with a fan wheel with axial admission. The aim of the invention is to create a magnetic flow meter that can be produced inexpensively and is distinguished by a low electronic expenditure as well as a low energy requirement. The object of the invention is to develop a magnetic flow meter which can be installed in every pipeline, presents a low flow resistance to the fluid medium, permits only low pressure losses and does not raise any sealing problems. According to the invention, the object is achieved in that a fan wheel is supported axially symmetrically in a piece of pipe consisting of nonmagnetic material without axial lead-throughs and upon rotation produces a periodic change in a magnetic field, which is detected by a magnetic sensor installed outside the piece of pipe, and a measurement signal correlated with the rotation frequency is generated, which is counted electronically, stored or displayed by a counter subassembly. The magnetic field is generated by a permanent magnet attached to the fan wheel. <IMAGE>

Title: Hydraulic actuator
Inventor: ALTMANN UWE DIPL ING
IPC: B62D5/09
Filed: 1987-09-07
Abstract: The hydraulic actuator for axial pivot steering a motor vehicle has a double-acting synchronisation cylinder (25) whose pressure spaces (24, 26) are controlled by means of electromagnetically actuable control valves (19, 20, 30). The position of the piston rod (27) is input into an electronic control device (35). The latter is operatively connected to an on-board computer (36) which supplies the actual values for the rear axle position. The control valves are also actuated from the electronic control device, in particular with the intermediate connection of a position controller (39) and of a valve controller (40). A proportional choker valve (30) also has a displacement sensor (42) which signals its position to the electronic control device. The outflow of pressure medium out of the pressure space to be relieved at the synchronisation cylinder (25) is controlled by means of the proportional choker valve (30). In this way, an extraordinarily precise actuation for the rear axle steering of a motor vehicle is obtained. <IMAGE>
